Mitigation Strategies

To mitigate this vulnerability, ensure that you update your Apex One/SEP agent to the latest version provided by Trend Micro that addresses this issue.

Since exploitation requires prior ability to execute low-privileged code, restricting such access and monitoring for suspicious local activity can help reduce risk.

Executive Summary

This vulnerability is an origin validation flaw in the Apex One/SEP agent. It allows a local attacker, who already has the ability to run low-privileged code on the system, to escalate their privileges. The issue is related to the process protection communication mechanism and is similar to another vulnerability identified as CVE-2026-45206.

Impact Analysis

If exploited, this vulnerability can allow an attacker with limited access to gain higher privileges on the affected system. This means the attacker could potentially perform actions that require elevated permissions, compromising the security and integrity of the system.
